To all whom it may concern.'

Be it known that I, HARVEY W. MORLEY, a citizen of the United States, and a resident of Angola, in the county of Steuben and State oi' Indiana, have made certain new and useful Improvements in Duplicating Devices for Type-Writing Machines, of which the following is a specification.

My invention relatesI to improvements in duplicating devices for typewriting machines, and it consists in the combinations, cmistructions, and arrangements herein described and claimed. l i f An object of my invention is to provide a device for duplicating the work done on a typewriting machine, which'dispenses with the necessity of using carbon copies, thereby eliminating the time necessary in insertingl and taking out carbon paper, eliminating the` cost of the carbon paper and doing away with the possibility of soiling the hands of the operator by the handling of the carbon paper. j

A further object of my invention is to provide a duplicator which jis provided with mechanism for making a duplicate copy which has the same spacing as the original or one hallc that of the original, at the will vof the operator.

A further object of my invention is to provide a duplicating device, the operating parts of which may be instantly disengaged .from the main or mastertypewriter.

(lt-her objects and advantages will appear in the following specification and thenovel ieatures of the device will be particularly pointed out in the appended claims.

j My invention is illustrated in the accompanying drawings forming part of this application in which similar reference char'- acters indicate like parts in the several views and in whicht Figure l is a plan view of the device, Fig. 2 is a front view of the device certain parts being broken away and other parts being shown in section, Fig. 3 is a section along the line 3 3 of Fig. 1 looking in the direction of the arrows, Fig. 4 is a section on the line l1.--4: of Fig. 5 looking in the direction of the arrows, Fig. 5 is a section along the line 5-5 of Fig. 4L looking in the direction of4 the 4arrows, Fig. 6 is a section along the line 6 6 of Fig. 5 looking in the direction of the arrows, Fig. 7 is a-perspective view of the clutch mechanism, a portion of the parts being shown in section, Fig. 8 isA a perspective View showing the means for connecting the keysof the master typewriter with the operating parts of the duplicator, Fig. 9 is a section through .the paper holder roller, part of the roller being shown in side elevation, Fig. 10 is a perspective View showing the connection between the paper holder rollers of the master typewriter and the duplicator, Fig. 11 is a perspective view of the drive sprocket for the paper holder rollers, Fig. 12 is a perspective view Vof the means for journaling and locking the shaft of the paper holder rollers, Fig. 13 is a perspective view showing one end of the paper holder and the means for tearing o the paper, Fig. la is a section along the line 14-14 of Fig. 3, and Fig. 15 is a perspective view of a modified form of the connecting mechanism between the main typewriter and the duplicator.-

In the present application I have embodied claims relating to the duplicating mechanism. Claims relating to the means for mounting the paper rolls and feeding the paper therefrom have been embodied in a separatedivisional application Serial No. 9298iled February 19, 1915.

In carrying outmy invention I provide a typewriter of any suitable make. In the drawings I have indicated a typewriter of*v the so-called basket type, but it will be undei-stood that the same principlefof operation might be applied to typewriters of other forms without departing from the spirit of the invention.

In Fig. l the keyboard of the main ory master typewriter is shown at 1, this key- .board being provided with the usual keys 2.

Disposed at one side of the master typewriter is a second typewriter` `In this second typewriter-the keyboard 1 has no keys. In fact the keyboard itself might be dispensed with as :Ear as the keys themselves are concerned except that downwardly projecting portionsthereof form convenient bearings for the rocklshafts which operate the type bars. For this reason 'I prefer Jto-make use of machines which have a keyboardV from which the keys are removed. A third typewriter having a keyboard 1y may also be provided and in fact other typewriters might be added, these additional typewriters being mere duplicates of the one adjacent the master typewriter.

llO

' stems 8 which are The frames of the master typewrter'and the duplicator immediately adjacent are con-l nected securely together as by means of a front plate 3 and a metallic band 4 running rearwardly therefrom between the two typewriters. The upper part of the frames of the master typewriter and the duplicator immediately adjacent is connected by means of a bar such as that shown at 5. In order to further bind the two machines together so that they may form a rigid unitary structure, braces 6 may be secured tothe bottoms of the frames yof the two. machines, these braces being secured to a common base 7, as

shown in Fig. 2. Securing devices 3X, 4",

5X and 6X similar to the securing .devices 3, 4, 5sand 6 are provided for holding-the adjacent duplicators together.

The means for connecting the keys 2 of the master typewriter to the working parts of the duplicators is clearly shown in. Fig. 8. In this figure' the keys 2 are provided with pivotally connected at 9 are rigidly secured... to of these rock shafts 11 usual arm 12 which is to arms`10 which rock shafts 11. Each is provided with the connected by means of a link 13 with the type bar (not shown) in the usual manner.-

It will be observed, however, that each of the rock shafts 11 is provided with an L- shaped arm 14 which is connected by means of a link 15 with an arm 16 on the rock shaft l17 of the nearest duplicator. A similar link 18y may extend tothe corresponding rock shaft of the next duplicator, so that when pressed on the master typewriter the rock shaft of the master typewriter corresponding to'f the key and also the rock shaft of the. duplicator corresponding to the key will be rock shaft 17 has an arm 12X which is connected by a link 13 with a type bar similar to the type bar which is operated by a pressure of the. key on the 'master typewriter. Turn buckles such as that shown at 19 are rovided for adjusting the effective lengths ofy and 18. Each key ofthe master the links 15 typewriter is connected with the adjacent duplicator in precisely the same manner.

As will be seen f om Fig. 6 the shaft 2O of the platen 21 of t e master typewriter'is extended beyond the bearing 22 and beyond the stop 23 carried by the framework 24 and is provided with a gear wheel 25 which is securely fastencd'to the shaft by means of a pin 26 or in an)7 other suitable manner. The shaft 20 has a reduced portion 20 arranged to enter a socket 27R of the shaft-27 which bears the platen 21", f the adjacent duplicator. The shaft 27 ears a gear -28 having ahhub 29 loosely mounted on the shaft 27 and provided withl a circumferential groove 30 in which a yoke 31 is arranged to extend. This yoke is borne by a lever 32 which is pivotallv mounted at 33 (see Fig. 1) on the with the 20 which bears the The duplicator rock 49. (see Fig. 12).

bar 5 which connects the master typewriter with the adjacent duplicator. The hub 29 has an extension provided with slots 34 arranged to receive guide members 35 formed integrally with the shaft 27 A pin 36 passes through the shaft 20 and the ends of the pin areadaptedto enter the slots 34 when the gear 28 is moved toward the gear 25.

Referring now to Fig. 5 it will be seen that the bearing 22 of the master typewriter is provided with an upwardly extending arm 37, the end of which forms a bearing 38 for a shaft- 39 disposed parallel with the shafts 20 and 27. The opposite end of the shaft 39 is j ournaled ina bearing 40 of the duplicator typewriter similar to the bearing 38 of the master typewriter. Loosely mounted on the shaft 39 is a sleeve 41which bears two lgears 42 and 43 respectively and an intermediate sprocket wheel 44. The gear 43 is constantly in mesh with the gea." 25. The gear 28 may assume any' one of-three `positions,'to wit; that shown in-F ig. 5, in which it is in mesh gear 42; an intermediate position shownin dotted lines in Fig.5, in which it is out of mesh with the gear 42, or a position to the right in which the hub 29 is far enough over to cause the pin 36 on the shaft 20 to enter the slot 34. Now the relation of the gears 25, 43, 42 and 28 is such that when the device is in the position shown in Fig. 5 a rotative movement of the platen shaft gear 25 will cause a rotative movement of the shaft 27 of the duplicator to just half the extent of the angular rotation of the shaft 20. In other words, the gears 25, 43, 42 and 28 are reducing gears. `It will therefore be apparent that in line spacing,the movement of the platen to form a double space will result in a single space movement of the duplicator when the gears are in the position shown in Fig. 5.

Th llever 32 is providedv with a locking segment 45 (see Fig. 1) and this lever may assume any one ofthree positions. When it is thrown over to the right the gears are set as shown in Fig. 5; when it is in inter- -mediate position, then the gear 28 is out of mesh with the gear 42, and when it is thrown over to the left the clutch member 36 enters` connecting the two shafts 20 and 47. The opposite end of the alined row of typewriters is provided with a similar extension and arm. The upper end of the arm is recessed to provide a retaining socket for a shaft 48 which isheld in position by means of a hook sleeve 50 which is provided with ball bearings 51 at one end and with ball bearings .Disposed on the shaft is a members 52 is extended as shown at 53 to vform a sleeve and this sleeve is provided with anannular groove 54. The sleeve 50' is provided at one end with an enlarged portion having a pin 55. A spool 56 is provided with an L-.shaped slot 57 at one end (see Fig. 10) and is arranged to fit over the inner sleeve 50 and to be secured to the latter b v the bayonet joint formed b v the pin 55 in the slot' 57. This spool is provided with a longitudinal slot 5S (see Fig. 9).

I have described one of the paper rollers,

lbut it will be seen from Fig. 10 that each machineis provided with two rollers, an upper and a lower roller. The upper rollers are all disposed on the shaft 48 while the lower rollers are disposed on a shaft 59 which is carried by the arms 47 at a level which is substantially that of the' upper part of the extension 46 (see Fig. 1). This shaft 59 extends directly from oneupright v47 to the other. Between the master type'- writer and the adjacent duplicator is an H-shaped frame member 60 which may be secured by means of a laterally extending arm such as that shown at 61 in Fig. 10 to the carriage frame `of either the master 'typewriter or the duplicator or both. The ends of the H-shaped frame member 60 are forked as shown at 60x to enter the annular grooves such as those shown at 54 and 54X in Fig. 9, thereby causing a longitudinal movement of the rollers along their respective shafts whenever the carriages are moved.

Disposed loosely on the contiguous ends of the sleeves 53 and 53* (see Fig. 9) is'a sprocket wheel 62 having a central flange 62X which enters between the contiguous ends of the sleeves 53 and 53X so as to prevent longitudinal movement of the sprocket wheel on the sleeves, but which eloes not prevent rotary movement of the sprocket with respect to the sleeves. Springs such as those shown at 63 extend laterally over each side of the sprocket wheel 62 and are bent inwardly so as tomaintain a frictional engagement with the sleeves 53 and 53X. A sprocket chain 64 passes over the teeth of the sprocket wheel 62 and over the sprocket wheel 44 'which is disposed intermediate' o1 the gears 43 and 42. It will be apparent that any movement of the sprocket wheel 44 will be communicated to the sprocket wheel 62 and this movement in turnmwill be imparted to the rollers of both the master typel' writer and the adjacent duplicator through the medium of the springs 63."

Secured upon the rear parts of the carriages` 'are curved paper guides like that shown'at 65 in Figs. 3 and 13. These guides are provided with cut-away portions 65L as shown in Fig.. 13. Carried by the curved paper guide 65 on the master typewriter are arms 66 (see Figs. 3 and 13) which support a. 'plate 67. This plate forms a support for the typewritten matter as it comes from the platen. In order to guide it in position I provide Aan auxiliary plateor strip of metal near the bottoni of the plate G7 the lower ends of the plates 67 and 68 being bent in opposite directions, as shown at 67 a and 68n to form guide members into which the edge of the paper may be placed as it comes from the platen. Y,

The upper edge' 68b of the plate 68 constitutes a knife edge or cutting edge along which the paper may be torn or cut olf. At one edge of the plate 67 is a scale 69 (see Fi 2) which is provided with perforations 70. Slidable on this scale is a laterally eX- tending stop arm 71 which bears a spring actuated plunger 72 .having a thumb piece 73. The thumb piece 73 may be raised so as to permit the arm 71 to be adjusted in various positions along thescale, and when released will cause the plunger7 2 to enter one of the openings so as'to lock the stop arm 71 in adjusted positions.

From the foregoing'l description of the various parts of the device the operation thereof may be readily understood.

The spools 56 (see Fig. 9) are designed I to besupplied with paper wound therein in -a roll ofunbroken length. T he spool containing the 'roll is placed. on the lower shaft bv removing the latter from its beari-ngs and slipping the spools over their respective sleeves suoli as that shown at 50' in Fig. 9,

' and locking them in position by means of the bayonet joint, as described. t'will be understood that the paper, supply rolls are placed in position for the master typewriter as well as for the duplicators.y .The paper is then passed over the curved guides underneath theplatens Vof the 'respective typewriters and the edge of the paper on the master typewriter is passed into the guide- .desired to have the original sheet, efe., the

one on the master typewriter writenwith double space lines and the copies written with single space on the duplicators the lever 32 iis shifted into the position shown in Fig. 1.

*Now on operating the master typewriter. `i`n' the usual ymanner the duplica-tors will make duplicate copies of the original with l the exception that these copies will be single spaced instead of double spaced, as eX- master typewriter is -plained' It will be observed. that as the carriages of the machines travel forward .they will carry with them the paper rolls so that the platens of the typewriters and the paper rolls maintain their same relative,

positions. l

The lever 74 (see Fig. 2) is the ordinary lei/er b y means of which the platen. of the pmaster typewriter is rotated for line spacing 10 and by which 'the carriages of the typewriting machines ares moved when the en'd of a line is reached. It has been previously eX- plained how theA revolution of the'shaft 2Ov I of the master typewriter will cause the revolution of the shaft of the duplicatorfadjacent t0 it one half the .angular revolution of the shaft 20. If more than one duplicator is used the shafts of the platens of the duplicator-s are rigidly connected together.

When t-he upper end of the sheet reaches he stoparm ,the operator grasps the sheet and tears it off on the knife edge or tearing edge 68". The sheets which are thus torn ofi1 are' precisely of the same length.

The movement of the sprocket wheel 44 causes the revolution of the sprocket wheel 62 through the medium ofthe chain 64, as heretofore described, .and this causes the' revolution of the upper paper rollers. The duplicate records which are being made `on the platens of the duplicators are passed over the paper guides 65 and the ends of the paper are cut and are inserted in the slots,

58 of empty spools. The revolution of thespools by the frictional engagement of the springs 63 with the sleeve 53, 53x etc., causes the paper to be rolled up as fast as it is fed forwardly by the line spacing mechanism. Thus while sheets of uniform size are being torn oif froml the master typewriter a'convtinuous sheet containing duplicate copies of the letters or other matter written on the separate sheets is wound on the upper rolls of the duplicators.

Instead of tearing off the sheets from the supporting'means on the master typewriter the sheets may be passed directly from the platen over the guide 65 (see Fig. 13) and may be wound on a paper holder or spool carried by the upper rod 48 so that the matter written on the master typewriter 4may be kept on a roll of continuous length if desired.

InF ig. 15 I have shown a modified form of means for transmitting the movement of a key of the master typewriter to vthat of the duplicators. In this form the key 2k of the at the end of a laterally extending arm 11k. The arm .bears on a roller 9k on an arm 10k securedto arock shaft 15k. This rock shaft extends past the mechanism. of the duplicator and is provided.

filed with very little trouble.

key 2k of the master typewriter. The other keys are connected in the same. manner.

It will be seen that- I have provided a. device in which duplicate copiesof the original may be made, either having the same line spacing or` line spacing one half that of the originals., Moreover these duplicate copies `have the advantage of being as plainly legi ble as the original, since they are, in a sense,

original copies themselves. Most carbon copies are not as plain as Vthe original. The provision of means wherebythe duplicate copies may be rolled Aon paper rolls obviates the necessity of removing the duplicate and filing them away as they would have to be were carbon copies prepared. The whole record may be lifted r'out from the duplicators-when theroll is 4filled up and may be The device is positive in its action so that no matter what is written on the master typewriter a true record is made on the duplicators.

If it is desired to make'a 'single copy on` the master typewriter lWithout making duplicate copies, the lever 32 need only be shifted to the neutral position, c'. e. the central position. This disconnects the line spacing vmechanism of the 'duplicators from that of the master typewriter. It also disconnects the driving mechanism of the upper paper rolls of the duplicators. ,If for any reason it is desirable to turn the upper paper roller of either' the master typewriter or the duplicators relatively to one another, this may be accomplished since the rollers are held only frictionally by the springs 63. When, however, it is desired to have the rpllers turned in. unison the springs 63 ai'e"sufliciently strong to cause the revolution of the rollers as the sprocket 62 is rotated.

This device is primarily designed to be used in connection with an electrical or other power device for operating the keys. Such devices are common and the application of thev same to the keyboard of the master typewriter is well understood. I have found in practice that a single duplicator may be very easily operated by the manual manipulation of the master typewriter in the ordinary manner.
